A wealth of romantic and familial complications face a musician en route to Cuba in the comedy Cuarteto de la Habana. Walther (Ernesto Alterio) is a Spanish jazz musician who gets word from a woman in Havana named Lita (Mirtha Ibarra) that she is his mother, whom he hasn't seen since he was a baby. Walther, excited by the prospect of a family reunion, catches a flight to Cuba, where he meets Segis (Javier Camara), a man who is soon to marry Diana (Laura Ramos). When Walther meets Diana, it's love at first sight, but it turns out there's a hitch -- Diana is Lita's daughter, and though her father was not Walther's father, being half-siblings is still enough to throw a serious spanner into the works. Director Fernando Colomo previously received acclaim for his film The Butterfly Effect.~ Mark Deming, All Movie Guide
